Comment Re:Randomness can't come from a computer program (Score 1) 64

Most of us do have a need to transmit messages privately. Do you not make any online purchases?

Yes, but those have to use public-key encryption. I am sure of my one-time-pad encryption because it's just exclusive-OR with the data, and I am sure that my diode noise is really random and there is no way for anyone else to predict or duplicate it. I can not extend the same degree of surety to public-key encryption. The software is complex, the math is hard to understand, and it all depends on the assumption that some algorithms are difficult to reverse - which might not be true.

The problem with FM static is that you could start receiving a station, and if you don't happen to realize you are now getting low-entropy data, that's a problem.

There are many well-characterized forms of electronic noise: thermal noise, shot noise, avalanche noise, flicker noise, all of these are easy to produce with parts that cost a few dollars.

True randomness comes from quantum mechanical phenomena. Linux /dev/random is chaotic, yes, enough to seed a software "R"NG. But we can do better and devices to do so are cheap these days.

I wouldn't trust anything but diode noise for randomness. If I had a need to transmit messages privately, I'd only trust a one-time pad.

I was okay with the government flying it in SC, because 1) it was the battle flag, for soldiers, not the political flag of the Confederate States of America and 2) it was flying at the memorial for South Carolinian soldiers who died in the Civil War. It's a sign of respect for the men who died fighting for their home and neighbors. Most of them were poor people who didn't own slaves themselves, and were, like every other damn soldier ever, fighting a rich man's war for the rich man's interests, but died believing he was fighting for home and honor. I don't believe they should be dishonored.

I can understand, though, Wal-Mart and pals not wanting to sell flags. That's fine. They can sell or not sell whatever they want (within the law). But Apple is just fucking stupid, pulling it from video games set in the Civil War. Might as well replace the soldiers' guns with walkie-talkies, too.

Comment From TFA: (Score 4, Insightful) 213

Taubira doesn’t actually have the power to offer asylum herself, however. She said in the interview that such a decision would be up to the French president, prime minister and foreign minister. And Taubira just last week threatened to quit her job unless French President François Hollande implemented her juvenile justice reforms.

So, basically, "not going to happen".

The courts said you have no expectation of privacy one you put your data in the hands of a third party. Great! Let's convince all those "evil corporations" to store all their data in the cloud. Then the government can go after them any time they want. B-b

Comment Re:The Moon is the way to go (Score 1) 169

Why would you build a moonbase for a radiotelescope or gravity wave detector? What's the argument for dropping it into a gravity well (where it can be exposed to moonquakes and moon dust) and having people operate it when you can just have it unmanned and in space (Earth-Moon L2 for a radiotelescope, Earth-Sun L5 for a gravity wave detector) at orders of magnitude less cost and far greater effectiveness?

Every one of these sort of proposals just screams "I'm an excuse that was made up solely to give us a reason to go back to the moon". The most glaring is surely 3He mining, of course ;)

Comment Re:Part of why I didn't become an astronaut (Score 1) 169

We see the propulsion breakthroughs right now - there's a wide range of propulsion systems possible with current technology. Unfortunately, the turnaround on these sort of things is measured in decades (generally with a number well over "1"). And if it has any form of the word "nuclear" in the title, multiply the average time from conception to deployment by a large number.
